Oligospermia means your Husband sperms are less then 20 million per ml this is considered to be low sperm count,  now doctors prescribe clomid for men in case of male Oligospermia (male infertility) to improve sperm count and Motility,with the use of clomid pituitary Gland works better and like thus clomid regulate the hormones level basically, so when Hormones level come to normal range then improve the sperm count and motility. Follow to your doctor, doctor will see your husband semen report and he will observe  clomid results, and you are taking folic acid which is good for you also so i suggest you to follow to your doctor, hop for best
